Q-Box^®

Perfect protection of the environment.

The Q-Box^® is designed for plants that are at risk of dust explosions, such as filters, elevators or silos with K_St -Values

Application

The rectangular connection complements the dimensions of standard explosion vents, thus allowing it to be retrofitted to existing indoor and outdoor equipment. The sanitary cover protects the Q-Box^® against dust from outside sources. Q-Box^® is also suitable for outdoor application. Easy retrofitting: The dimensions of the Q-Box^® perfectly match the dimensions of REMBE^® standard explosion vents.

Sanitary Cover

protects the Q-Box^® against dust from outside sources.

Advantages

Flexible use of the Q-Box^® permits process-efficient plant design.
Reduces noise levels.
Perfect protection of the surrounding area.
Neither heat, dusts nor a dangerous pressure wave emerge from the vessel – everything stays in the Q-Box^®.
Cost-effective alternative to venting ducts. No running costs for venting ducts and external maintenance, a visual inspection is sufficient.
Integrated signalling unit for reliable monitoring.
Reduced downtime: Access to the protected system doesn't require a safety-related locking mechanism (LOTO).
Flexible solution for indoor and outdoor use.
Simple retrofitting to existing explosion vent installations.

Mechanism

The special stainless steel mesh filter inlet developed by REMBE^® cools the hot flame gases extremely efficiently (up to 1.500 °C (2.732 °F) or even 3.000 °C (5.432 °F) for metal dusts). This reduces the volume of gas ejected and extinguishes the explosion.
